[quartz] handle antialiasing correctly in stroke() and clip()

Browse source 
A CoreGraphics bug was fixed so strokes are no longer incorrectly
drawn with antialiasing disabled; we no longer have to ignore
antialiasing for stroke().  Also, antialiasing was not being
correctly set for clip().  This fixes both issues.
